Application filed June 11,

J My invention relates in' general to means "for handling shingles, and particularlyito a table-for inspecting shin les which are to be stained.

It is well known to those skilled in the'art that in the present methods of staining "shingles, an entire bundle of shingles is dipped'into the stain and impregnated therewith. After the shingles have been stained,

if they are inspected at all previous to be- 'ing'shipped, the bundle is opened and the shingles which are materially defective are rejected. 'Such a method not only causes a Waste of stain and shingles, but laboras well.

Ithas been an object of my invention to provide means whereby the shingles may be conveniently, accurately, and economically inspected previous to their being stained.

Another object has been to provide means 'wherebya bundle of shingles may be coniveniently divided into one-half bundles for "subsequent handling in staining and rebundling.

Another object has been to provide av de- "vice by 'means 'of which two men can convemently and accurately inspect a bundle iof shmgles in a very short time.

'Another'object of my invention has been to provide a table having a platform for supporting the bundle of shingles which shall "be vertically movable, thus keeping the top layers of shingles of the bundle at substantiallythe same point opposite the workers "until all of the shingles have been removed and inspected.

yMoreover, 'my device provides convenient means for stacking the shingles after they are inspected.

Furthermore, my inspection table is provided with a conveniently arranged box or bin along one side thereof for the convenient reception of defective shingles cast aside during inspection. v

The above objects and advantages have been accomplished by the apparatus shown in the accompanying drawing. In the drawm i ig. 1 is a side elevation of my device, partly in section.

Fig. 2 is an end elevation of the same.

ported between the side walls.

1930. Serial No. 460,450.

The device shown in the. accompanying 'dIflWlIlg comprises a table 5 having legs 6 connected together at their upper ends, preferably by means of the channel-irons 7,-and

at a point near their lower ends by means of channel-irons 8. V

A rigidly mounted vertical sleeve is supported, preferably by means ofchainnelirons 11, at the center of the table. The sleeve extends some distanceabove-the table aswell as some distance below, and thechannel-irons 'supportingit are secured preferably to the channel-irons 7 Slidably mounted within the sleeve 10 is a reciprocating shaft or tube 12 which has an inspection platform 13 fixed to its upper end. This platform is'of proper size to support-a full bundle 14 of shingles. Cross bars 19 are arranged, one at each-end'of the table, whereby "bundles of upon the-table while being worked upon. The'bottom end of the reciprocating shaft 12 extends some distance below the lower end of the'sleeve 10 and it is connected to the inner end 15 of an elevating arm 16 by means of-links 17 and a pin 18, which passes through the lower ends of the links'and also through the lower end of the reciprocating shaft 12. The elevating'arm may be made, as shown,

7 of channel-iron,-and preferably has the web 20 cut away at the inner end 15 so that the end flanges of the arm straddle the shaft12 as shown. 7

The-elevating arm 16 is pivotally attached to a shaft or tube 21 which is carried by'the channel-irons 8, and it has a counterwei ht 22 adjustably mounted-0n its outer end. lBy means of the adjustable counterweight, the full bundle of shingles may be counterbalanced. t

A shingle tray 25 is arranged at eachend of the table and opposite the platform13. ,These trays may be fixed to the table top, or they may be slidably-arranged, in :which event they are guided by angle-irons '26. Each of these trays is provided with two side walls-27 and with anfinclined back 28sup- This back is of suflicient height so-as-to have its upper edge come substantially :opposite the upper different sizes will lie firmly NORTH :ToNAwANnA, NEW, YORK, A COR- portion of the bundles of shingles when such bundle is resting on the table and the table has thereby been depressed to its lowermost position. The bottom 29 of each of the trays is preferably formed of a plurality of flat bars 30 which are in interspaced relation and held in place by means of the rods 31 and 32 which pass through the bars and through the side walls 27. This arrangement provides adequate support for the inspected shingles but permits any splinters, sawdust, and small pieces of shingles to drop therethrough, as the layers of shingles are placed within the tray.

Arranged preferably at one side of the table is a strap hanger 33 which may be provided with an upturned end 34, which serves to support the straps 35. The strap of the bundle of shingles is opened at one side after the bundle of shingles is placed upon the table 13 and it is allowed to remain-on the table until all of the shingles of the bundle have been removed, whereupon it is then hung upon the strap hanger 33. Arranged at one side of the device, and on the side which is preferably opposite the strap hanger 33, are tWo boxes or bins 40, each of which preferably has a bottom 41 and only two sides 39 and 42. Each of these boxes is supported upon channels 42 extending crosswise of the machine. These boxes are thus conveniently positioned and are for the purpose of receiving the defective shingles which are discarded by the inspectors.

When the device is to be put into use, a bundle of shingles is placed upon the platform 13, and the weight of the bundle will cause the platform to be depressed, thus substantially counterbalancing the weight of the full bundle of shingles, as shown in the drawing. The strap 35 of the bundle of shingles is now opened by one of the operators at the side opposite the strap hanger, and the top strap is thrown over to the strap hanger side where it remains until the complete bundle is inspected. After all of the shingles havebeen inspected and removed, the strap is dropped onto the strap hanger 33 by one of the inspectors; An inspector being stationed at each end of the table, each inspector now alternately removes from his side of the bundle'one layer at a time, pulling the shingles toward him by grasping them by the butts, carefully examining the shingles for defects, which he casts aside into the defective box 40. The good shingles are drawn forwardly by the operator over the shingle tray 25 and are allowed to slide downwardly into the tray with their faces lying parallel to the back'28, the butts striking the bottom bars 29 of the tray. As the shinglesfall and strike the bars with considerable impact, loose splinters and sawdust are thus jarred loose from the shingles and allowed to fall between the bars-29. Shin- 'gles are shown in position in the trays by means of dotted lines. As the shingles are removed from the platform, the weight of the diminished bundle is reduced and the counterweight 22 tends to move the platform upwardly. The upward movement of the platform, however, is controlled by one of the operators by means of his foot or leg, whereby the movement of the table will be such as to always keep the top layer of shingles at the most convenient elevation. After the entire bundle has been inspected, each inspector grasps his half of the inspected bundle and places it upon suitable means for conveyance to the staining apparatus.

Obviously, some modifications of the details herein shown and described may be ,made without departing from. the spirit of my invention or the scope of the appended claims, and I do not, therefore, wish to be limited to the exact embodiment herein shown and described, the form shown being merely a preferred embodiment thereof.

aving thus described my invention, what I claim is:

1. A shingle inspection table, comprising a vertically reciprocating platform, and a shingle tray arranged at each side of the platform, each tray comprising side walls, an

inclined bottom formed of flat interspaced vice, and a centrally arranged strap hanger 7 provided at the opposite side of the device.

3. A shingle inspection table, comprising a vertically reciprocating platform, gravity actuated means for counterbalancing said platform as it supports a full bundle of shingles and for raising it as the shingles are removed therefrom, and a shingle tray arranged at each end of the platform, each tray comprising side walls, an inclined bottom, and a b ack extending upwardly from the bottom and inclined inwardly from its lower edge toward the axis of the platform.

In testimony whereof, I have. hereunto signed my name.
